Answer:
36°, 72°, 108°, 144°
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
sum the parts of the ratio, 1 + 2 + 3 + 4 = 10 parts
Divide 360° by 10 to find the value of one part of the ratio
360° ÷ 10 = 36° ← value of 1 part of the ratio, then
2 parts = 2 × 36° = 72°
3 parts = 3 × 36° = 108°
4 parts = 4 × 36° = 144°
The 4 angles are 36°, 72°, 108°, 144°
